Attached is a file from our converter that seems to be giving trouble loading. We’re getting the error:
Welcome to Mantid - Manipulation and Analysis Toolkit for Instrument Data LoadMuonNexus started Error in execution of algorithm LoadMuonLog: invalid string position Error in execution of algorithm LoadMuonNexus: invalid string position
These files were generated from our old binary format using a NeXus converter.

The attached file appears to be corrupted. Anders can you please e-mail me a copy so I can investigate.

It fails because the old muon file has a start_time with a space between the date and time rather than a 'T' as is the case for the newer muon files. MuonNexusReader.cpp expects the 'T' and throws an exception, when it can't find it (to turn it into a space). It should be simple to make it work with both kinds of dates.
